CINCINNATI -- Brewers pitching prospect Wily Peralta exited Thursday's game after 5 1/3 innings with tightness in his right biceps, and the club will have to decide in the coming days whether to send him back out for one more start.
"We'll see how he is [Friday] and what it looks like," manager Ron Roenicke said after Milwaukee's 2-1 loss to the Reds. "It's a shame for him, because he was throwing the ball great."
But Peralta was not 100 percent after the second inning, when he told veteran third baseman Aramis Ramirez that his right arm was bothering him. Ramirez passed word to Roenicke, and staffers kept a close eye on Peralta over the ensuing innings.
The right-hander looked just fine, surrendering only two singles and no runs through five innings, but he looked wild while striking out opposing pitcher Mat Latos to begin the sixth. When the Brewers went around the horn after the play, the infielders wouldn't return the baseball to Peralta. Head athletic trainer Dan Wright visited the mound, and Peralta immediately exited.
The 23-year-old is tentatively scheduled to pitch again on Tuesday against the Padres.
"I think I'm going to be OK for the next one," Peralta said. "I was getting ahead of the hitters, throwing strikes, keeping the ball down. I was pretty happy with the way I threw the ball today. [The injury] is something you don't want to happen, but I will try to get myself ready for the next one. I feel fine, and I'm going to start throwing tomorrow and let's see."
Said Ramirez: "He wanted to stay out there, but it made no sense. Not for a young man like that."
Roenicke said Brewers medical staffers were "not concerned" about the issue bothering Peralta in the long term.
